DISINFEGTING APPARATUS.

Application filed February 21, 1913.

To all whom it may concern Be it known that I, DANIEL J. DORAN, a citizen of the United States, residing at Brooklyn, in the State of New York, have invented certain new and useful Improvements in Disinfecting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has relation to an improved form of dispensing device for deodorizing or for disinfecting fluids, and particularly to such as are intended to be attached to water closets and the like for de livering limited quantities of such fluids in connection with the water used for flushing purposes.

One object of my invention is to provide improved means for controlling the rapidity of flow of the disinfecting or deodorizing fluid from the usual inner container to the outer casing.

Another object is to provide a device of the special character above described which is adapted to be so applied to the flush pipe that the force of the water in flushing shall be used to scour the thick deposit of disinfecting fluid out of the bottom of the outer casing, and, after thoroughly miXing it with a proper proportion of water, shall deliver it through the flush pipe to the closet below.

The invention is illustrated in a preferred form in the accompanying drawings, where;

Figure 1 is a general elevation showing the relation of my device to the closet system, Fig. 2 is a vertical section through my dispensing apparatus, Fig. 3 shows the adjustable drip discharge in longitudinal section and Fig. 1 is a plan view of the inner container.

The outer casing 10, of usual form is preferably applied to a wall by means of brackets 11, close to the flush pipe 12, leading from the usual elevated reservoir 13 to the bowl 1 1.

lVithin the casing 10, and preferably supported upon brackets 15, is an inner container 16, having an opening 17 at its bottom, limited on two sides by descending walls 18. The opening in question is closed by a drip plug preferably composed as shown of a cylindrical body 19, cut away at Specification of Letters Patent.

20 to receive the nuts 21, which engage bolts 22 depending beneath the container 16 and passing through the plug. This plug is provided with a wicking so mounted as to project into the disinfecting fluid within the container 16, and to be locally compressed 111 a manner capable of adjustment as to degree of pressure, by suitable changes in the nuts 21. A variety of forms of wick and of modes of mounting the same may be adopted without departing from the spirit and scope of my invention. In the preferred form shown the construction for this purpose is as follows :-The plug 19 is provided with a median circumferential groove, 23, preferably of a semicircular cross section or approximately so, and within this groove is placed a round wick 24:, whose endsproject upward under or through the opening 17. This wick is held in place on the plug before assembling by any suitable means, and 1 prefer to bind it on by means of a band 25 of textile material extending over a considerable portion of the surface 9f the plug. This distributes the fluid by capillary attraction. The rapidity of flow of fluid withdrawn by the wicking is very accurately adjusted and determined by adjusting the tightness of the nuts 21, and thereby regulating the degree of pressure exerted by the edges of the walls 18 upon the round wick, which should be made large enough to project to a material extent beyond the confines of the groove 23. The fluid passing out through the wick 2+1 and band 25 falls, drop by drop, into the bottom of the outer casing, and may be distributed to any outside receiver in any desired manner, so far as my invention, as thus far described, is concerned.

lVhere the full benefit of my preferred invention is to be made available in connection with the flushing of water closets and the like, the construction shown in Figs. 1 and 2 (or its equivalent) is employed in its entirety. Here the casing 10 is mounted close beside the flush pipe 12, which is so pierced as to admit two pipes 26, 2'7, between it and the casing below the container 16. A firm connection is preferably supplied by means of the band 28, fastened, for instance, by the screw 29. The upper tube 26 is preferably inclined as shown, and provided, within the pipe 12, with a cu away portion, concave upward, and so placed as to intercept a portion of the downward stream of water passing through the pipe 12 when flushing occurs. The effect of this construction is that, each time flushing takes place, a certain amount of water enters the lower part of the casing 10, through the tube 26, and, as it enters in a somewhat violent jet, it scours the thick disinfecting fluid oil' of the bottom of the casing and thoroughly stirs and mixes it with the limited volume of water which may enter. Consequently, when the main flushing stream has passed through the pipe 12,. the concentrated mixture in the casing 10' is free to run out through the. tube 27, until the level of the mixture falls below 27'.

Thus the mixture is admitted finally only to.

between said plug and the edges of said walls, substantially as described.

2. In a drip disinfector, an outer casing, a fluid container within the same having an opening in its bottom limited by depending walls, a substantially cylindrical plug having a circumferential groove, a wick within said groove, means for supporting said plug with the ends of said wick under said opening, and means for varying the pres sure exerted by said walls upon said wick, substantially as described.

In a drip disinfector, an outer casing, a fluid container within the same having an opening in its bottom limited by depending walls, a substantially cylindrical plug having a circumferential groove, a wick within said groove, a capillary band for holding said wick in place, means for supporting said plug with the ends of said wick under said opening, and means for varying the pressure exerted by said walls upon said wick, substantially as described.

In testimony whereof, I afiix my signature, in presenceof two witnesses.
